A key feature of this project is the integration of a web-based Simple Network Management
Protocol (SNMP) tool. SNMP is a widely used protocol for monitoring and managing network
devices. The SNMP tool implemented in this project provides real-time insights into network
traffic patterns and device performance, enabling network administrators to make informed
decisions and quickly respond to potential issues. This tool offers features such as traffic
monitoring, alert notifications, and detailed reports on network performance, significantly
enhancing the network management capabilities.
This project was undertaken by a team of five dedicated members, each contributing their expertise
in various aspects of the project, from system design and implementation to testing and validation.
By integrating optical and Ethernet technologies, advanced bandwidth management, and a robust
SNMP tool, this project aims to set a new standard in office LAN management, providing a
scalable and reliable network solution for modern enterprises. Extensive testing and validation
ensured the network's resilience under varying traffic conditions. This project also sets a foundation
for future advancements in corporate network management solutions. As businesses continue to
rely more heavily on digital solutions, this project emphasizes the importance of adaptable network
structures. The knowledge and experience gained through this endeavor will serve as valuable
assets in future projects. It represents a proactive approach to meeting the ever-evolving demands
of network infrastructure in today’s fast-paced world.

PROJECT DESCRIPTION
The project, "Office LAN Management with Optical & Ethernet, Bandwidth Control, and
SNMP," aims to establish a robust and scalable network infrastructure tailored to the dynamic
needs of small to medium-sized office environments. Utilizing the versatile MikroTik RB941
router, this setup combines optical and Ethernet technologies to deliver high-speed, reliable data
transmission. By leveraging both wired and wireless connections, the network accommodates
various devices and configurations, making it adaptable to future growth and technology
upgrades.
A primary focus of the project is implementing effective bandwidth control to manage network
resources efficiently. Through the MikroTik RB941 router, specific bandwidth limits are set for
each device, ensuring fair allocation and prioritizing essential services. This configuration
reduces the risk of network congestion, providing uninterrupted access to critical applications
and enhancing overall productivity. Bandwidth control plays a pivotal role in maintaining
network stability and allowing seamless operation for multiple users with diverse needs.
In addition to bandwidth management, the project incorporates key network security and
management features. Firewall rules are meticulously configured to secure the network,
preventing unauthorized access and protecting sensitive data. Network Address Translation
(NAT) facilitates smooth internet access across all devices, while precise IP routing optimizes
connectivity for local and remote resources. The inclusion of SNMP (Simple Network
Management Protocol) capabilities further enhances network oversight, enabling real-time
monitoring of device performance and traffic patterns. This SNMP integration equips network
administrators with valuable insights, allowing them to make informed decisions and promptly
address potential issues.
The "Office LAN Management with Optical & Ethernet, Bandwidth Control, and SNMP" project
provides a comprehensive solution that not only meets immediate connectivity requirements but
also prepares the network for future growth. By combining advanced bandwidth management,
security protocols, and SNMP monitoring, this setup delivers a resilient, high-performance LAN
infrastructure suitable for Dhaka’s fast-paced business environment.

METHODOLOGY
The methodology outlines the step-by-step approach followed to implement the "Office LAN
Management with Optical & Ethernet, Bandwidth Control, and SNMP" project. Each step is
designed to ensure the effective setup of network components, optimize resource management,
and enhance network monitoring. This section covers the configuration and testing procedures
carried out to build a scalable and secure network infrastructure.
3.1 Hardware Setup and Initial Configuration
The initial setup of the MikroTik RB941 router involves preparing the hardware, accessing the
router’s configuration interface, and establishing basic network settings to ensure connectivity.
This section provides a detailed, step-by-step guide to help us get the router ready for more
advanced configurations.
3.1.1 Powering the Router & Connecting to a Computer
Connect the MikroTik RB941 router to a power source and establish a connection with a PC
for configuration access.

(Figure 1: MikroTik hap lite RB941 router)

3.1.2 Accessing & Configuring Network Interfaces with WinBox

Opened the WinBox application on the computer. WinBox is MikroTik’s utility for managing
and configuring their devices with a user-friendly interface. After opening up WinBox we will
select the routers and then fill up the login credentials and hit connect. The default credentials
are written on the backside of the router. In this case, its default username is “admin” and its
password is “123456”. We can change it later according to our preference.

(Figure 2: WinBox interface showing available MikroTik devices for connection by MAC or IP address.)

If everything is ok, we will be logged into the router and can manage things and configure
things according to our preference now. First, we will Adjust the router clock. Setting the router
clock ensures accurate logging, scheduled tasks, security and compliance, and network
synchronization. To do this we need to click on “system>clock” from the left sidebar.

(Figure 3: Accessing Clock settings in WinBox (System > Clock)

 5

After this, we will see an interface where we can change Time-Zone, Date & Time. We will
change this according to our choice and hit apply.
The next thing we will do is rename the interface to identify each interface without any
hesitation for better management. To do this we will click on “Interfaces” from the left sidebar.
It will show all interface default names. To change it we just need to click on the interface
which name we want to change.

(Figure. 4: Renaming interface to ether1_WAN in WinBox (Interfaces > ether1))

3.1.3 Creating a Bridge for LAN Ports

Creating a bridge for LAN ports on the MikroTik router is essential when we want multiple
Ethernet ports to act as part of a single network. In this setup, adding ports like ether2, ether3,
and ether4 to a bridge (named bridge1_LAN) allows them to communicate as if they are on the
same physical network. This is particularly useful in office environments where we want
seamless connectivity between devices across different LAN ports.
Here’s a step-by-step process to create and configure a bridge for the LAN ports:
In the WinBox interface, go to the Bridge menu on the left sidebar. This is where we can
manage bridge interfaces, which essentially act as virtual switches that link multiple physical
interfaces together.
Adding a New Bridge:
• Click the Add button (usually represented by a “+” sign).
 6

• In the new bridge window, set the Name of the bridge to something descriptive, like
bridge1_LAN, to easily identify it as the main LAN bridge.
• Click Apply and OK to save the bridge configuration. This action creates the bridge
interface but does not yet associate any physical Ethernet ports with it.

(Figure. 4: Creating and naming a bridge interface as bridge1_LAN in WinBox.)

Assigning LAN Ports to the Bridge:

• After creating the bridge, go to the Ports tab within the Bridge menu.
• Click Add to add each Ethernet port that should be part of the bridge.
• Select bridge1_LAN as the Bridge for each port.
• For the Interface, select each LAN port in turn (e.g., ether2_LAN, ether3_LAN, and
ether4_LAN).
• Click Apply and OK for each port to save the configuration.
• This configuration links ether2_LAN, ether3_LAN, and ether4_LAN to bridge1_LAN,
allowing them to function as part of the same local network.
Verifying Bridge Configuration:
Once all LAN ports are assigned to bridge1_LAN, confirm the configuration by checking that
each port appears under the Ports tab associated with bridge1_LAN.
We can test the bridge by connecting devices to each of the LAN ports and verifying that they
can communicate with each other over the network.
 7

(Figure 5: Assigning LAN ports (ether2_LAN, ether3_LAN, ether4_LAN) to bridge1_LAN in WinBox.)

3.2 Setting Up IP Addresses, Firewalls and Routes

In this section, we configure the MikroTik router with essential IP settings, firewall rules, and
routing protocols to establish a secure and organized network. Assigning IP addresses to the
LAN and WAN interfaces allows devices within the LAN to communicate effectively, while
the firewall rules protect the network from unauthorized access. Finally, setting up routing
enables LAN devices to access external networks seamlessly.
3.2.1 Setting Up IP Addresses
To configure the LAN IP for bridge1_LAN and the WAN IP for ether1_WAN, first navigate to IP
> Address in WinBox. Click on the Plus (+) icon to add a new IP address.
In this case, we assign 101.10.10.1/24 to bridge1_LAN as the LAN gateway IP, allowing devices
on the LAN to use it as their primary gateway. For the WAN interface, we assign 192.168.0.2/24 to
ether1_WAN to connect to the upstream network or internet source. The /24 subnet mask
(equivalent to 255.255.255.0) specifies that the first 24 bits of the IP address are fixed for network
identification, leaving the remaining 8 bits for device addresses within the network. This setup
allows up to 254 usable IP addresses (from 101.10.10.1 to 101.10.10.254) for devices on the LAN,
providing ample room for connected devices in most office environments.

To finalize the configuration, ensure both IP addresses appear correctly in the Address List with
the appropriate interfaces (bridge1_LAN and ether1_WAN). This establishes the LAN gateway and
enables the router to communicate with external networks through the WAN interface.
 8

(Fig. 6: Configuring IP addresses for bridge1_LAN and ether1_WAN in WinBox)

3.2.2 Setting up Firewalls

To set up the firewall, we will again click on IP in the WinBox menu, then select Firewall.
From there, navigate to the NAT tab and click on the Plus (+) button to add a new rule. This
action will open a configuration popup where we can define the NAT settings.
In the popup window, we go to the General tab and set the Chain to srcnat. This tells the router
that this rule applies to outgoing traffic originating from our internal network.
Next, we switch to the Action tab and set Action to masquerade. This enables dynamic source
NAT, meaning the router will automatically replace the source IP address of outgoing packets
with the router's WAN IP. This is particularly useful for setups with a dynamic IP, as
masquerade will adapt if the WAN IP changes.
Once we’ve configured these settings, we click Apply and OK to save the rule. Now, all
devices on the local network will be able to access the internet, and external devices will see
traffic as originating from the router’s public IP, providing an added layer of security by hiding
internal IP addresses.
To configure Filter Rules for controlling traffic within the network, we will again go to IP >
Firewall in the WinBox menu. This time, instead of the NAT tab, we will work within the
Filter Rules tab.
Adding Accept Rules for Specific IPs:

• Click on the Plus (+) button to add a new rule. This will open the rule configuration
window.
 9

• In the General tab, set Chain to forward, which controls traffic that is being routed
through the router.
• Set Src. Address to the specific IP address we want to allow (e.g., 101.10.10.2,
101.10.10.10, 101.10.10.18, and 101.10.10.20 for individual devices).
• In the Action tab, set Action to accept. This will allow traffic from these specific IP
addresses.
• Click Apply and OK to save each rule.
Adding a Drop Rule for Other Traffic:
After configuring the accept rules, add a final rule to drop any other traffic from the
101.10.10.0/24 network that doesn’t match the previous rules.
• Click the Plus (+) button to add a new rule.
• In the General tab, set Chain to forward and Src. Address to 101.10.10.0/24 (the entire
subnet).
• In the Action tab, set Action to drop. This rule will block any traffic from devices within
the LAN subnet that are not covered by the previously accepted rules.
• Click Apply and OK to save the rule.
These filter rules ensure that only the specified IP addresses (101.10.10.2, 101.10.10.10,
101.10.10.18, and 101.10.10.20) are allowed to forward traffic, while all other traffic from the
subnet 101.10.10.0/24 is blocked. This adds a layer of security by limiting network access to
specific devices.

(Figure 7: Configuring a firewall filter rule in WinBox to allow traffic from the IP address)
 10

3.3.3 Adding IP Routes

To allow devices on the LAN to reach external networks (like the internet) through the
WAN interface, we need to set up a default route. This routing rule tells the router where to
forward traffic destined for addresses outside the local network.
Open the Route List:

• In WinBox, navigate to IP > Routes. This opens the Route List window, which
displays current routes and allows us to add new ones.
Create a Default Route:
• Click the Plus (+) button to add a new route.
• In the Dst. Address field, enter 0.0.0.0/0. This is the default route for all traffic
not specifically destined for internal IPs, covering any destination.
• Set the Gateway to the IP address of the next hop, which is typically the upstream router or
ISP gateway IP. In this example, we enter 192.168.0.1, the gateway for ether1_WAN.
• Click Apply and OK to save the configuration.
With this default route, any traffic from the LAN intended for external networks will be
directed through ether1_WAN using 192.168.0.1 as the gateway. This setup enables internet
access for devices on the local network.

(Figure 8: Adding a default route (0.0.0.0/0) to forward traffic through the WAN gateway (192.168.0.1)
in WinBox.)
 11

3.4 Bandwidth Control Configuration

To ensure fair distribution of network bandwidth among users and prevent any single device
from consuming excessive resources, we use Queues in WinBox to set bandwidth limits for
each device.
Access the Queue Settings:

• In the WinBox menu, go to Queues. This will open the Queue List window, where
we can add and manage bandwidth control rules.
Adding a New Queue:

• Click on the Plus (+) icon to add a new queue for bandwidth management. This opens
the Simple Queue configuration window, where we can define the bandwidth limits.
Setting Basic Queue Information from the General tab:
• Name: Enter a name for the queue (e.g., "Farabi") to identify the device or user.
• Target: Set the target IP address of the device for which we want to control bandwidth
(e.g., 101.10.10.10 for Farabi’s device). This ensures that the bandwidth limits only
apply to this specific IP address.
Configuring Bandwidth Limits:

• Target Upload: Set the maximum upload speed for the device. For example, we
might set this to 15M to allow a maximum upload speed of 15 Mbps.
• Target Download: Set the maximum download speed. For instance, setting 10M
limits the device's download speed to 10 Mbps.
These values ensure that the selected device cannot exceed these speed limits, preventing
network congestion and ensuring that other users have access to sufficient bandwidth.
Burst Settings (Optional):
For advanced control, we can configure burst settings to allow temporary speed boosts for
devices when bandwidth is available:

• Burst Limit: Set the burst speed for download and upload (e.g., unlimited to allow a
temporary speed increase).
• Burst Threshold: Define the threshold at which bursting begins. For example, setting it
to 5M means the burst will activate when the usage stays below 5 Mbps.
• Burst Time: Set the duration of the burst. A higher value allows the device to enjoy
faster speeds for a longer period when bandwidth is available.
 12

Saving the Configuration:

• Once we have entered all the desired settings, click Apply and OK to save the queue.
This rule will now appear in the Queue List and will be actively controlling the
bandwidth for the specified device.
Repeating for Additional Devices:

• Repeat the above steps to create queues for other devices as needed. For instance, we
might set up queues for other users, such as "Mili" with a 10M limit, "Ramisha" with
5M, "Faysal" with 1M, and "Mashrika" with 2M.
By implementing these queues, we control the upload and download speeds for each device,
ensuring fair bandwidth distribution across the network. This setup is particularly useful in
office or home environments where multiple users need reliable internet access without one
device hogging the bandwidth.

(Figure 9: Configuring bandwidth limits for devices in WinBox using Simple Queue settings)

3.5 Checking LAN And WAN Connection

To verify that both the LAN and WAN connections are working correctly, we can perform a
series of ping tests from both sides. This ensures that devices on the local network can
communicate with the router and access external networks (like the internet) through the WAN.
 13

Testing LAN Connectivity:

• From a device connected to the LAN (such as a computer or mobile device on the same
network as bridge1_LAN), open the command prompt (on Windows) or terminal (on
macOS/Linux).
• Use the ping command to test connectivity to the LAN gateway. For example:
ping 101.10.10.1
• A successful ping indicates that devices on the LAN can communicate with the router,
confirming the LAN setup is correct.

(Figure 10: Verifying LAN connectivity by pinging the router’s LAN IP 101.10.10.1)

Testing WAN Connectivity:

• To test the WAN connection, open the Terminal in WinBox on the MikroTik router.
• Use the ping command to check connectivity to an external IP address, such as Google’s
DNS server:
Ping 8.8.8.8
• If the ping is successful, this confirms that the router has access to the internet through
the WAN interface.
 14

(Figure 10: Verifying WAN connectivity by pinging an external IP 8.8.8.8)

We see that we are getting a response from the ping command, indicating successful
connectivity. This response confirms that our LAN and WAN configurations are correctly set
up, allowing internal devices to communicate with the router and access external networks. The
positive ping results from both LAN and WAN interfaces signify that the routing and NAT
rules are functioning as intended, ensuring seamless data flow between the internal network and
the internet. This verification step is essential as it confirms that devices on the local network
can reliably reach external resources, completing our initial connectivity setup.
3.6 SNMP Integration
To enhance network monitoring capabilities, PRTG Network Monitor was integrated with the
MikroTik RB941 router using SNMP. This setup provided a centralized platform for real-time
monitoring, alerting, and data visualization, which greatly assisted in maintaining and
troubleshooting the network.
3.6.1 Installation and Initial Setup
PRTG was downloaded from the official Paessler website, where a free trial version was
available for testing. After downloading, the software was installed on a Windows-based
server/pc, which would serve as the monitoring station. Upon launching PRTG, the web
dashboard was accessed using the default username and password provided by PRTG.
 15

3.6.2 Configuring SNMP and Enabling Auto Discovery

Once logged into the PRTG web dashboard, the Auto Discovery feature was enabled. This feature
automatically scans the network to identify active devices and add them to the monitoring setup,
streamlining the initial configuration. For more focused monitoring, specific IP addresses,
including the MikroTik router’s IP, were added manually to monitor critical nodes directly.

(Figure 11: All nodes discovered by PRTG)

3.6.3 Setting Up Sensors and Monitoring Metrics

PRTG's integration with SNMP enabled the addition of various sensors tailored to monitor
essential network parameters. Some of the key sensors configured included:
• Ping Sensors: To measure response times and connectivity status for the monitored
devices. These sensors provided real-time data on network latency and packet loss.
• Traffic and Bandwidth Sensors: These sensors tracked the data flow through the router,
allowing detailed insights into the network’s bandwidth usage and identifying any spikes
or irregular traffic patterns.
• System Health Sensors: Monitoring CPU load, memory usage, and uptime to ensure the
router’s performance remained stable under various loads.
3.6.4 Real-Time Monitoring and Alerts
PRTG’s intuitive dashboard displayed live data from the network, with graphical representations of
response times, bandwidth usage, and device health. Alerts were configured with specific
thresholds for critical metrics. For example, alerts were set for high CPU load or excessive
bandwidth usage, which helped in responding promptly to potential issues before they escalated.
 16

(Figure 12: Monitoring Nodes in Real-Time)

3.6.5 Data Visualization and Analysis

PRTG offered historical data analysis and reporting features, with visual aids like graphs and
sunburst diagrams that highlighted network structure and activity. These visual tools were
particularly useful for reviewing trends over time, identifying peak usage hours, and
understanding network behavior. They also served as a valuable resource for optimizing
network performance based on historical usage patterns.

In conclusion, integrating PRTG with SNMP on the MikroTik router provided a comprehensive
and effective monitoring solution. The setup allowed for detailed oversight of network activity,
proactive alerts, and insightful data analysis, ensuring a reliable and well-managed network
environment.
 17

RESULTS AND DISCUSSION

System Performance
During testing, the system demonstrated strong stability and resilience. The MikroTik RB941
router maintained reliable connections across both LAN and WAN interfaces, ensuring that devices
on the local network could communicate effectively and access external networks without
interruptions. The router’s processing capacity handled various network loads efficiently, making it
a viable choice for small to medium office environments with moderate bandwidth demands.
Traffic Monitoring Efficacy
The integration of the SNMP tool proved effective for real-time traffic monitoring. SNMP
enabled network administrators to gain insights into device performance, bandwidth utilization,
and traffic patterns across the network. The system successfully generated alerts for unusual
network activity, allowing for prompt action to prevent potential issues. The reporting features
also allowed for detailed analysis of network health, which facilitated a better understanding of
usage trends and the identification of high-traffic devices.
Bandwidth Management Outcomes
The bandwidth control feature worked as intended, distributing network resources equitably
among users. By setting specific limits on upload and download speeds for individual devices,
the system prevented any single device from monopolizing bandwidth. This balanced allocation
resulted in an improved user experience, as each device received consistent network access
without experiencing significant slowdowns, even during peak hours. This outcome confirms
the utility of the MikroTik’s simple queue feature in environments where fair bandwidth
distribution is critical.
Challenges and Solutions
A few challenges arose during the configuration and deployment phases. Initially, firewall rules
required fine-tuning to ensure that both LAN and WAN traffic flowed as expected, particularly
for devices with specific access needs. Additionally, minor issues with connectivity
interruptions were encountered, mostly due to incorrect initial setup of NAT and routing. These
issues were resolved by adjusting the firewall and NAT rules and re-evaluating the default route
settings. Overall, the learning curve for MikroTik's configuration tools was manageable, and the
challenges were addressed with straightforward solutions.
 18

of this project. Implementing advanced security protocols, such as VPNs and additional firewall
rules, could further enhance network security, particularly in larger or more sensitive environments.
Additional monitoring tools could be considered to extend the analytical capabilities of the
network, providing deeper insights into traffic trends and potential security threats. Fine-tuning
bandwidth control options could also provide more flexible and customizable allocation strategies,
adapting the network more precisely to user needs and application types.

In conclusion, the MikroTik RB941 router offers a cost-effective and efficient solution for office
LAN management. With further development, this setup could provide even greater adaptability,
security, and performance, making it a scalable option for larger network environments as well.
